Some more NAND cleanup and small fixes.

Patch by Rick Bronson, 15 Jun 2005

code and in SoC code). Boards using the old way have CFG_NAND_LEGACY and
BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
implemented for these boards.

so we can use them to, e.g., check the existence of a file with
"if ls foo; then this; else that; fi" in the hush shell
Patch by Andreas Engel, 16 August 2005

Minor coding style cleanup.

Old, obsolete and duplicated code was cleaned up and replace by the
new partitioning method. There are two possible approaches now:
* define a single, static partition
* use mtdparts command line option and dynamic partitioning
Default is static partitioning.

a single #define.

March 13, 2005); new configuration options CONFIG_JFFS2_LZO and
CONFIG_JFFS2_LZARI are added. Both are undefined by default.

Using external watchdog for KUP4 boards in mpc8xx/cpu.c;
load_sernum_ethaddr() for KUP4 boards in lib_ppc/board.c;
various changes to KUP4 board specific files

* Fix SL811 USB controller when attached to a USB hub

* Fixes for SL811 USB controller:
  - implement workaround for broken memory stick
  - improve error handling

* Increase packet send timeout to 10 ms in cpu/mpc8xx/scc.c to better
  cope with congested networks.

  (JFFS2 speed enhancements) because of using non-public
  data (PHYS_FLASH_SECT_SIZE)

* Patch by Travis Sawyer, 23 Apr 2004:
  Fix VSC/CIS 8201 phy descrambler interoperability timing due to
  errata from Vitesse Semiconductor.

  JFFS2 speed enhancements:
  - repair header CRC calculation in jffs2_1pass.c
  - add eraseblock size to the partition information to skip empty
    eraseblocks if we find more then 4k of free space.
  - The JFFS2 scanner is now fast enough to remove the spinning wheel
    so #ifdef-ed out.
  - add watchdog calls in long running loops

* Patch by Philippe Robin, 22 Apr 2004:
  Fix ethernet configuration for "versatile" board

* Patch by Kshitij Gupta, 21 Apr 2004:
  Remove busy loop and use MPU timer fr usleep() on OMAP1510/1610 boards

* Patch by Steven Scholz, 24 Feb 2004:
  Fix a bug in AT91RM9200 ethernet driver:
  The MII interface is now initialized before accessing the PHY.

* Cleanup PCI ID's

  - add support for microblaze processors
  - add support for AtmarkTechno "suzaku" board

* Configure PPChameleon board to use JFFS2 NAND support.

* Added support for JFFS2 filesystem (read-only) on top of NAND flash

  - show PCI clock frequency on MPC8260 systems
  - add FCC_PSMR_RMII flag for HiP7 processors
  - in do_jffs2_fsload(), take load address from load_addr if not set
    explicit, update load_addr otherwise
  - replaced printf by putc/puts when no formatting is needed
    (smaller code size, faster execution)

* Patch by Scott McNutt, 02 Jan 2004:
  Add support for the Nios Active Serial Memory Interface (ASMI)
  on Cyclone devices

* Patch by Andrea Marson, 16 Dec 2003:
  Add support for the PPChameleon ME and HI modules

* Patch by Yuli Barcohen, 22 Dec 2003:
  Add support for Motorola DUET ADS board (MPC87x/88x)

  add support for cramfs (uses JFFS2 command interface)

  - Added Motorola CPU 8540/8560 support (cpu/85xx)
  - Added Motorola MPC8540ADS board support (board/mpc8540ads)
  - Added Motorola MPC8560ADS board support (board/mpc8560ads)

* Minor code cleanup

  add FAT support for IDE, SCSI and USB

* Patches by Gleb Natapov, 2 Sep 2003:
  - cleanup of POST code for unsupported architectures
  - MPC824x locks way0 of data cache for use as initial RAM;
    this patch unlocks it after relocation to RAM and invalidates
    the locked entries.

* Patch by Gleb Natapov, 30 Aug 2003:
  new I2C driver for mpc107 bridge. Now works from flash.

* Patch by Dave Ellis, 11 Aug 2003:
  - JFFS2: fix typo in common/cmd_jffs2.c
  - JFFS2: fix CFG_JFFS2_SORT_FRAGMENTS option
  - JFFS2: remove node version 0 warning
  - JFFS2: accept JFFS2 PADDING nodes
  - SXNI855T: add AM29LV800 support
  - SXNI855T: move environment from EEPROM to flash
  - SXNI855T: boot from JFFS2 in NOR or NAND flash

* Patch by Bill Hargen, 11 Aug 2003:
  fixes for I2C on MPC8240
  - fix i2c_write routine
  - fix iprobe command
  - eliminates use of global variables, plus dead code, cleanup.

  - remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)

  the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
  boards, version 153 for Rev. 200 boards).

* Patch by Vladimir Gurevich, 12 Mar 2003:
  Fix relocation problem of statically initialized string pointers
  in common/cmd_pci.c

* Patch by Kai-Uwe Blöm, 12 Mar 2003:
  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by
    writing beyond the block boundaries.
  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.
